SN65DSI84: Test pattern OK but no picture otherwise.

SN65DSI84: There is no display when use SN65DSI84 to change MIPI to LVDS

Hi Team,

There is no display when use SN65DSI84.

The solution is T7'sMIPI(1920x720)->SN65DSI84->LVDS ->DS947->DS948->LCD Display（LVDS).

Verification process:

1. We directly sent the LVDS signal to 947 and the image can be displayed (it was verified that there was no problem with 947/948); 

2. We connect the Qualcomm's MIPI signal (1280x720)  to the DSI84, and there was a horizontal snowflake dot; 

Special note:

We use T7 to do double screen display with two signals

Channel 1: double lvds-> ds947-> ds948-> LCD display (normal display)

Channel 2: MIPI(1920x720)->SN65DSI84 turn dual lvds-> ds947-> ds948-> LCD display (no image display)

Could you please help for this? Thanks a lot!
